What Turbotech does

Turbotech is a French aerospace startup founded in 2017 and headquartered at the Toussus-le-Noble aerodrome near Paris. The company develops high-technology aeronautical propulsion solutions for light aviation and hybrid-electric aircraft, and claims to be the first company in the world to introduce regenerative turbines for aeronautical applications. Its core intellectual property is a patented microtube heat exchanger, developed over 10 years of R&D in partnership with French manufacturer Le Guellec, which recovers heat from exhaust gases and reinjects it into the combustion chamber to dramatically reduce fuel consumption while preserving turbine reliability.

Turbotech has commercialized two product lines based on this regenerative technology: the TP-R150 turboprop (104 kW / 141 hp, 86 kg fully equipped, 3,000-hour TBO, multi-fuel including Jet-A1, Diesel, UL91, AVGAS, Bio-Fuel and H2, FADEC-controlled, single-lever operation, 19 l/h fuel burn at eco-cruise) and the TG-R90 turbogenerator (85 kW continuous electrical output, 64 kg, generating 630–800V DC to enable hybrid-electric propulsion with up to 10× the range of full-electric aircraft when paired with batteries). Both products target light aircraft, helicopters, UAVs, and hybrid-electric VTOL platforms.

The company's business model is hardware sales of turboprop engines and turbogenerators, complemented by service and support through an expanding global dealer network. It pursues a hybrid go-to-market: direct sales to aircraft manufacturers (JMB Aircraft for the VL3 turbine, Bristell for the XL8, GOGETAIR for the G750) and OEM-embedded integration with hybrid-electric aircraft developers (notably Ascendance's Atea VTOL, combined with Safran electric motors and Exoes thermal management). Pricing is not publicly disclosed and follows a contact-based sales model. Strategic backing includes Safran (also a co-developer via the BeautHyFuel H2 turbine consortium with Air Liquide), BPI France, Innovacom, DGAC, Île-de-France region, and France Relance. The company held demonstration flights of the VL3 Turbine at the Paris Air Show (Le Bourget) in June 2025 and signed an STC program agreement with FFPLUM/FFA in October 2024 to certify turbine operation in light aviation.

Revenue model

1. Turboprop Sales: Sale of TP-R150 turboprop engines to power light aircraft, helicopters, and drones. The turboprop is sold directly to aircraft manufacturers and operators in the general aviation sector.
2. Turbogenerator Sales: Sale of TG-R90 turbogenerator systems to hybrid-electric aircraft developers and integrators. The turbogenerator serves as an onboard electrical genset enabling hybrid-electric propulsion architectures.
3. Service and Support: Dealer network providing support and expertise to all Turboprop and Turbogenerator users, likely including maintenance, spare parts, and technical services.

Core offering

Turbotech designs, develops, and manufactures regenerative turbine propulsion systems for light aviation and hybrid-electric aircraft. Its two core product lines are the TP-R150 turboprop engine (141 hp, 86 kg) for light aircraft, helicopters, and drones, and the TG-R90 turbogenerator (85 kW, 64 kg) as an onboard electrical generator for hybrid-electric propulsion architectures. Both products are built around a proprietary microtube heat exchanger that recovers exhaust heat to dramatically reduce fuel consumption.

Product overview

Turbotech is a French company offering two core propulsion product lines based on its proprietary regenerative turbine technology with microtube heat exchangers: the TP-R150 Turboprop (141 hp, 86 kg) for powering light aircraft, helicopters, and drones; and the TG-R90 Turbogenerator (85 kW, 64 kg) as an onboard electrical genset for hybrid-electric aircraft architectures. Both products leverage regenerative turbine technology to achieve very low fuel consumption while maintaining turbine reliability and longevity.

Emerging players

• ZeroAvia: UK/US startup developing hydrogen-electric propulsion for commercial and light aircraft. Comparable to Turbotech as another early-stage company pursuing alternative aviation propulsion, with a different architectural choice (hydrogen fuel cells vs. Turbotech's H2-capable gas turbine) but the same BEAUTY/H2 aviation tailwinds and OEM partnership model.
• MagniX: US startup developing electric propulsion systems (magni250, magni500) for fixed-wing aircraft and seaplanes. Comparable to Turbotech's TG-R90 as an alternative propulsion supplier to the emerging hybrid-electric and electric aviation market, but with a battery-electric architecture rather than turbine-based generation.
• Evolito: UK startup spun out from YASA supplying axial-flux electric motors and powertrain components for eVTOL and electric aircraft. Adjacent peer to Turbotech's TG-R90 in the hybrid-electric propulsion supply chain for eVTOL OEMs, addressing the same Ascendance-class customer segment with a different subsystem.
• H3X Technologies: US startup building high-power-density integrated electric motors and motor controllers for eVTOL and electrified aircraft. Comparable to Turbotech as a propulsion supplier targeting the eVTOL/hybrid-electric aircraft value chain, focused on the electric side of the powertrain where Turbotech positions the gas-turbine side.
• Aura Aero: French aircraft manufacturer developing the Integral family of light aircraft and the ERA hybrid-electric regional aircraft. A comparable French ecosystem peer, both as a potential customer for Turbotech's engines and as a fellow emerging player in sustainable light/regional aviation propulsion.

Broad incumbents

• Pratt & Whitney Canada: Incumbent maker of the PT6 turboprop family and PW100/200 turboshafts that dominate light aviation, helicopter, and regional aircraft propulsion. Directly comparable to Turbotech on product category (turboprops/turboshaft) and target customer base, but with an entrenched installed base and full MRO network that Turbotech must compete against.
• Rolls-Royce: Through its Rolls-Royce Power Systems and civil aerospace businesses, produces light/medium turbine engines including the M250 and RR300 turboshafts used in light helicopters and aircraft. A broad incumbent peer competing with Turbotech's TP-R150 in the same customer applications with a mature certification and support footprint.
• Safran Helicopter Engines: Safran makes the Arrius and Arriel turboshaft families for light helicopters and is also a Turbotech investor and BeautHyFuel partner. A direct competitor in turboshaft/light helicopter propulsion, but with full type certification, global MRO, and a much broader product portfolio.
• Aerojet Rocketdyne (L3Harris): Through its propulsion heritage, Aerojet Rocketdyne (now part of L3Harris) manufactures turbine-based power and propulsion systems including small turbomachinery. Comparable to Turbotech on underlying gas turbine technology and aerospace propulsion know-how, but operating at much larger scale and across rocket propulsion as well.

Direct peers

• Continental Aerospace Technologies: US manufacturer of piston and diesel engines for the general aviation and light aircraft market, the segment Turbotech targets with the TP-R150. Highly comparable customer base and aircraft platforms, but Turbotech is pitching a turbine alternative to Continental's incumbent piston engine lineup.
